Some possible causes of nighttime leg pain include improper posture, sitting or standing for extended periods of time, pregnancy, Parkinson's disease and endocrine disorders. While anyone is at a risk of suffering from nocturnal leg pain, middle aged or older people are the most commonly affected group, according to Cleveland Clinic.
Pregnant women may experience nocturnal leg cramps because of additional weight. As their weight increases, more pressure is exerted on muscles and bones, which may be the reason they experience painful episodes during the night.
People who are overweight or obese may experience nighttime pain due to exerting pressure on certain regions of the legs. Conditions such as calcium deficiency can also lead to poor development of bones and muscles, which leads to painful sensations.
Sitting for long or standing on hard surfaces for extended periods can cause muscle strain. Other issues that may lead to nocturnal leg pain include alcoholism, dehydration, statins and neuromascular disorders.
To avoid nighttime leg pain, drink fluids to keep the body hydrated. Engaging in frequent exercises and watching body weight are important factors to keep in mind, notes WebMD. Eating a balanced diet, avoiding overuse of muscles and keeping proper posture while sitting or standing may help in treating the condition.
